(2020) Pengaruh Penambahan Nanohidroksiapatit Tulang Sapi Terhadap Kekerasan Model Gigi Berbahan Dasar Self Cured Acrylic sebagai Media Pembelajaran Keterampilan Klinis Prostodonsia. Sarjana thesis, Universitas Brawijaya.
Abstract
Latar Belakang: Model gigi buatan pabrik yang digunakan sebagai media pembelajaran keterampilan preparasi gigi di preklinik saat ini belum sepenuhnya mampu merepresentasikan sifat mekanik dari gigi asli. Self-cured acrilic dengan penambahan nanohidroksiapatit tulang sapi diharapkan dapat menjadi bahan potensial yang sifat mekanik kekerasannya mendekati gigi asli sebagai upaya pengembangan media pembelajaran yang baru. Tujuan: Mengetahui kekerasan permukaan model gigi self-cured acrylic dengan dan tanpa penambahan nanohidroksiapatit tulang sapi. Metode: Penelitian ini menggunakan pendekatan Observational Analytic dengan rancangan penelitian posttest only control group design. Hidroksiapatit hasil sintesis metode basah dipreparasi menjadi berukuran nano dengan prosedur ball milling. Sampel acrylic block berjumlah 24 berbahan dasar self-cured acrylic (12mm x 12mm x 3mm) meliputi 6 buah tanpa penambahan bahan dan 6 buah pada masing masing penambahan nanohidroksiapatit 2%, 5%, dan 8%. Sampel diinkubasi dalam aquades pada suhu 37oC selama 24 jam, lalu dilakukan uji kekerasan menggunakan alat Vicker’s Microhardness Tester. Hasil: c. Pada pengujian statistik Oneway Anova didapatkan nilai signifikansi p=0,000 dimana p<0,05. Dari hasil uji statistik didapatkan perbedaan nilai kekerasan yang signifikan dari penambahan nanohidroksiapatit tulang sapi pada bahan self-cured acrylic. Kesimpulan: Penambahan nanohidroksiapatit tulang sapi pada bahan self-cured acrylic dapat meningkatkan kekerasan permukaan secara signifikan, sehingga berpeluang menjadi media pembelajaran model gigi baru yang lebih baik bagi mahasiswa preklinik bidang prostodonsia.
English Abstract
Background: The factory-made dental model that is used as a medium for learning preparation skills for preclinical teeth is not currently able to represent the mechanical properties of natural teeth. This self-cured acrylic with the addition of bovine bone Nano hydroxyapatite is expected to be a potential material whose hardness mechanical properties end in natural teeth as an effort to develop new learning media. Method: Uses approach Observational Analytic with research posttest only control group design. Hydroxyapatite resulted from the wet method synthesis was prepared into Nano-sized using ball milling procedure. There are 24 acrylic block made from self-cured acrylic (12mm x 12mm x 3mm) includes 6 pieces without added ingredients and 6 pieces each addition of 2%, 5%, and 8% Nano hydroxyapatite. Samples were incubated in distilled water at 37oC for 24 hours, then the hardness test was carried out using a Vicker's Microhardness Tester. Results: The results showed that the average surface hardness value of self-cured acrylic 15.99 VHN; self-cured acrylic with the addition of 2% Nano hydroxyapatite 17.32 VHN; 5% for 17.66 VHN: and 8% for 18.30 VHN. Oneway Anova statistical test a significance value of p = 0.000 where p <0.05. From the statistical test results, it was found that the difference in hardness values was significant from the addition of Nano hydroxyapatite to self-cured acrylic material. Conclusion: The addition of bovine bone Nano hydroxyapatite to self-cured acrylic can significantly increase surface hardness, so that it has the opportunity to become a better learning media for new dental models for preclinical students in the field of prosthodontics.
